I have waited a while before posting a review for this as i saw a number of people claiming that it breaks after a short while. Well i have had mine (16000mAh version) for 10 months now and it gets a lot of use. I charge my phone off it, two tablets and a variety of other small gadgets. It has not only performed faultlessly over the time i have had it but it has never actually run out! I have had a number of similar things over the years and they always make big claims and hardly ever live up to them eg I had supposedly 4.4Ah chargers from a different manufacturer and i even emailed them to clarify the capacity and weather that also took into account the various losses in up/down voltage conversion (3.6 to 5 etc) and charging/standby losses but they assured me that the figures were not 'fudged in their favour'. But using bench measuring equipment, it was easy to prove the stated capacity was BUNK! Anyway, i digress, This one is great! Buy it! you'll never look back.
I saw a question relating to charging it while using it, so while i'm here, Yes it does that on the 16Ah model, I do that with it regularly

Actually, this item seems solid. I've only got it around 16th October so a bit too early to comment on but so far, I've used it about 3 times now and it seems to hold power. It's impressed me at this stage but still watching. I think it's a really good product. It comes with a usb cable but no bag. It really doesn't look like something that will disappoint. I will recommend it. It's about 5.35" ie almost the size of a Samsung s4 in length tho but one quarter inch longer than it. In width, the s4 is definitely wider but the item is obviously sturdy. I will definitely recommend 95% until I come back in a month or two's time to say otherwise if I have to.

30/10/14; Update: The more I get to use this item the more I love it but it charges forever tho, over 12hrs! But I really don't mind. Item is really beautiful. It holds charge very well and doesn't discharge it quickly, which is a big plus to it.

23/10/15: Update: Still loving this item. It still retains power. Still can't fault it. Loving it. Highly recommended.

This is amazing. My family have a variety of battery packs but NONE are as good as this. This successfully and quickly charges my phone 3 times over or more before requiring a charge itself.

I stick the pack on charge overnight until full battery and don't have to worry about it for such a long time.

The only downside to this pack is that it's quite large, but still fits in lots of my smaller handbags. It's rather heavy too. If TeckNet were to produce something this powerful but slightly smaller that would be fantastic.

I have recommended this to all of my friends and a friend who borrowed it says she's going to buy one herself because it's so good!

A must-have portable charger.

Fantastic product thats perfect for travelling and being on the go.
Holds loads of power, have charged an iPhone6s more than 6 times when the battery is fully charged.
Light function is handy and charging lights give an accurate indication of remaining power.
An easy to use product that is taken everywhere.

I honestly can't believe just how fantastic this power bank is.
I have a galaxy S5 and the power bank is roughly the same size, thicker though.
Yes it takes a long time to fully charge the power bank but that's because it holds enough juice to power a small town! I charged my S5 four times when it was on less than 30% battery remaining and the power bank still had more than a third of its juice left in it. And that was over a month too so when you charge the power bank up it doesn't drain when you're not using it. Certainly not to any great extent anyway.
It charges the phone as fast as if it were charging from the mains too.
I saw one review saying don't lose the charging lead that comes with it because charging times are dramatically increased when using other leads. That's only because that person obviously bought a cheap lead with reduced capacity. I've used the power bank with several other quality leads with no problem.
I'd be very surprised if there were anything better on the market than this item at this price. I love it!
And you can charges two things at once from it!

Excellent quality product. Worked well out of the box. Now over 3 years and
still carries 6 phone charges. Because I rely extensively on Phonemaps when
out walking, it is an essential piece of safety kit to keep your phone and maps alive
when hikes are longer than expected

It lasts for ages and I used it for charging my phone for four days whilst I was away from home. It is one of the best portable chargers I have used.
